MOUNTING 0T SPINDLES OF SELF-ACTING MULES.

Application filed October 30, 1924. Serial No. 746,718.

To all whom it may concern:

Be it known that 1, JAMES LEVER Bosn- TON, a subject of the King of Great Britain, residing at Kay Street l/Vorks, Bolton, in the county of Lancaster, England, have invented new and useful Improvements Relating to the hlounting of Spindles of Self-rlcting Mules, of which the following is a specification.

The invention relates to improvements relating to the mounting of spindles of self acting mules and has for its object to provide an improved mounting for the spindle bolster.

In the specification of British Letters Patent No. 161,769 granted to me was described and claimed a mounting for spindles consisting of two plates, one superposed and welded or otherwise secured upon the other and both secured to the bolster bracket, the opposite edges of the plates being bent over and the front edge of the top plate which was the thinner of the two plates was cut or sheared true and the present invention constitutes an improvement or modification thereof.

According to the present improvement the double plate is dispensed with and a single plate substituted therefor the edges being bent over at either side and one of said edges is extended downwardly for some distance in contact with a downward extension of the bolster bracket for example to a depth approximately equal to the width of the plate or th reabouts and at its extreme lower edge the plate is turned at right angles in order to give rigidity.

The spindle hearing or bolster is bolted or otherwise fixed to the deeper side of said plate by which means the construction is simplified while the rigidity of the bolster plate is retained or increased.

Band in order that the said improvement 1112 y be more clearly understood and readily carried into effect I will now proceed aided by the accompanying drawing more fully to describe the same.

The drawing illustrates an end elevation of part of a bolster bracket of a mule having the present improvement applied tiers-to.

Referring to the drawing, 1 represents the spindle, 2 represents the spindle bearing or bolster, and represents the bolster bracket.

According to the present improvement a single plate 4+. is employed, which plate is bent longitudinally thereof to form a pair of flanges at and P at right angles to the plate, one at each side of the bolster bracket 3, the flange ll being of greater width than the flange l" and bent at right angles adjacent to its lower edge to form another flange 49, in order to give greater rigidity to the structare.

The bolster bracket 3 is provided with a downward extension 3, with which the flange i of the plate e is maintained in contact and is securely fixed thereto by a screw 5, the spindle hearing or bolster being in turn fixed by means a screw 5 to said flange 1". This flange is provided for the purpose of facilitating the alignment of the spindles whereby the construction of the spindle mounting is. simplified while the rigidity of the bolster plate is retained or increased.

What I claim as my invention and desire to secure by Letters Patent is:

In a spinning mule, the combination of a spindle-bearing bracket having a downward extension, a plate secured to said bracket and bent longitudinally thereof to form a pair of flanges at right angles to the plate, one of said flanges being wider than the other and maintained in contact with the downward extension of said bracket, said ider flange being bent near its outer edge to form another tlange at right angles to said wider flange, and a spindle bearing mounted upon said wider flange and said downward extension.

In testimony whereof I have signed my name to this specification.

JAMES LEVER RUSHTON.
